Patent DE-3149409-A1 (DE)
Title: Broadcast receiver
Inventor: SHIRATANI YUJI
IPC: H04B1/10
Filed: 1981-12-14
Abstract: The broadcast receiver according to the invention first receives a selected or set broadcast transmitter, whose tuning data are transferred by a control unit (16) from a first memory (26) to a first and second data field in a second memory (28). If the control unit (16) identifies a deterioration in the receive level of the set transmitter by means of a receive level detector circuit (14), it successively transfers tuning data for the remaining transmitters stored in the first memory (26) to the first data field (28-1) of the second memory (28) in order to identify the transmitter which supplies a satisfactory receive level, while muting the broadcast receiver. The transmitter identified in this way is then received, while the control unit (16), periodically and at extremely short time intervals in which the broadcast receiver is muted, exchanges the tuning data contained in the first data field (28-1) for the data in the second data field (28-2) and checks the receive level or receive condition of the respective received transmitter. When the receive level is recovered, the initially received transmitter is once again tuned in, the tuning data of the latter being transferred to the second data field (28-2). <IMAGE>

IPC: F28F13/18
Filed: 1982-01-07
Abstract: A process for the surface treatment of aluminium articles, in particular aluminium parts in vaporisers of air-conditioning units, serves to obtain hydrophilic properties. To improve the hydrophilic properties in such a way that especially the heat exchange effect in the use of the aluminium articles in air-conditioning units is improved, the process is characterised by a first treatment of the surface(s) of the aluminium article to form a chemical coating and by a subsequent treatment with a solution of a compound consisting of or containing silica(s) and/or silicate(s) and/or colloidal siliceous earth(s).

IPC: B60T8/50
Filed: 1982-03-18
Abstract: On the basis of antilock control systems, in which the rotational speeds of the wheels are detected by measuring sensors, fed to a slip monitoring electronic unit and compared with a reference signal proportional to the speed of travel, in which between a brake pressure source and wheel brake cylinders first valves are arranged to break this connection and the wheel brake cylinders can be connected by way of second valves and restrictors to an unpressurised tank, the first and second valves being actuable by output signals of the slip monitoring electronic unit and in which means are provided for influencing the pressure gradients in the pressure reduction phase (t4-t2), the invention, in order to achieve an approximately constant pressure gradient, proposes to assign bypass lines (19, 20) to the restrictors (15), which lines in the pressure reduction phase (t4-t2) can be released by third valves below an adjustable brake pressure (P2). By these measures the pressure gradient in the low pressure range is significantly increased. <IMAGE>

Title: Brake-actuating device for vehicles which can be used in two opposite directions of travel
Inventor: SCHROECK MANFRED
IPC: G05G1/01
Filed: 1982-11-10
Abstract: A vehicle which can be used in two opposite directions of travel has two couplable brake pedals (1, 2; 1a, 2a) for each direction of travel (7, 8), which serve for steering braking. Each brake pedal (1, 2; 1a, 2a) has a lever arm (11, 12; 11a, 12a). The lever arms (11, 11a; 12, 12a) of each side of the vehicle each bear a pin (13, 13a; 14, 14a), by which they engage in slots (15, 15a; 16, 16a) of their common rail (17, 18). Each rail (17, 18) is articulated on the piston rod (19, 20) of the master brake cylinder (9, 10) assigned to the respective side of the vehicle. With decoupled brake pedals for one direction of travel, steering braking can be undertaken with them at any time, without having to pay heed to the coupling state or any hindering of movement of the brake pedals for the other direction of travel. <IMAGE>

Title: Circuit arrangement for switching an electric-motor drive on and off
Inventor: RADDANT HANS-JOACHIM DIPL ING
IPC: H02P7/03
Filed: 1983-02-19
Abstract: A circuit arrangement is proposed for switching an electric-motor drive on and off, preferably into or between two defined limit positions, in that the drive motor is intended to be electrically braked during switching off, with as little delay as possible, by short-circuiting the motor winding. To this end, the circuit arrangement comprises two relays (14, 15) which are connected by means of in each case one changeover contact (14a, 15a) to a connecting lead (12, 13) of the drive motor (11), and the break contacts (14c, 15c) of the relay (14, 15) being connected to one another at one terminal and the make contacts (14b, 15b) being connected to one another at the other terminal of a supply voltage. When the drive is operated, the one relay (15) is initially switched on for a specific rotation direction, and the motor is connected to the voltage via the changeover contact (15c) of this relay. When the motor (11) is switched off, the other relay (14) is additionally also switched on, and the motor (11) is electrically braked, subject to the short pull-in delay of the relay (14), via the changeover contact (14a) of said relay (Figure 1). <IMAGE>

Title: Circuit arrangement for switching systems controlled on party lines, in particular for telephone dispatcher systems
Inventor: KOLLAR JANOS DIPL ING
IPC: H04Q5/02
Filed: 1983-03-16
Abstract: The invention relates to a circuit arrangement for switching systems controlled on party line systems, in particular for telephone dispatcher systems, which contains a programmed control unit and also an address and data bus system between the control unit and the different functional and peripheral units. A line set is provided to ensure the signal flow between the line and the peripheral units, and furthermore a sensing unit indicating the condition of the peripheral units, a programmable selector unit, an audio-frequency signal receiver, a programmable signal transmitting unit and a tone caller and ringing unit are provided. The activation and deactivation of the secondary stations associated with the party line are performed in the control unit connected downstream of the party line. The control unit processes the information received from the functional and peripheral units according to the used, stored and/or hard-wired program, and performs the control functions relating to the operational requirements imposed on the system. In this way, the functional and peripheral units can be simplified, and there is no need for the direct link between the units, which in any case prevents the possible system variations and would require complicated wiring.
Patent DE-3312807-A1 (DE)
Title: Hydraulic cylinder, in particular rotary actuator for implements such as reversible ploughs or the like
Inventor: OBERT HERBERT
IPC: A01B3/421
Filed: 1983-04-09
Abstract: The invention proposes a hydraulic cylinder which can be used, in particular, as a rotary actuator for implements such as reversible ploughs or the like. The particularly simple switchover of the piston from a pulling movement into a pushing movement is accomplished by the displacements of a longitudinal slide, displaced mechanically via the piston, by a control unit in such a way that a control flow acts on the longitudinal slide and displaces the control edges in such a way that a reversal of flow of the hydraulic fluid occurs. The longitudinal slide is held until the hydraulic fluid is cut off. The end position of the piston in the cylinder space is achieved by closure of the cylinder space by means of a hydraulically pilot-controlled mechanical non-return valve.

Title: Device for storage of bar-shaped workpieces
Inventor: HEIERMANN KLAUS DR ING
IPC: B65G1/04
Filed: 1983-05-20
Abstract: A device (1) for the storage of bar-shaped workpieces (2) of different lengths is used predominantly for the automatic, computer-controlled supply of a cutting machine with these workpieces (2). To this end, bay compartments (5) are arranged opposite and above one another in bay aisles (6), and a lift truck (7) and a lifting device (8) are provided for loading the bay compartments (5) and for removing the workpieces (2) from the bay compartments (5). Each time a new workpiece (2) is introduced into the entire device (1), its length is determined in a length-measuring device (9) by recording the distance between the outside ends of such a workpiece (2). The value determined in this way is input into the memory of the computer for storage control. This length is thereby determined in a very precise manner, in such a way that the computer can select a workpiece (2) as accurately as possible when a request is made for a workpiece (2) to be processed on a cutting machine (Fig. 1). <IMAGE>
